UNITED STATES NATI-IANIEL L. CLARKE, OF ENDWELL, NEW YORK.

vtocarme VALVE.

Application filed November 25, 192e. serial No. 603,315.

To all 'whom t may Gomera.'

Be it known that I, NATHANIEL L. CLARKE, a citizen of the United` States, residing at i Endwell, in the county of Broome and State gasoline in automobiles and other mechani'- cal devices and also for controlling the flow of other liquids; and another object is` to provide a simple and most effectiveform of valve look and yet most effective in 'all practical results.

With these and other 'objects in view, my

invention consists in certain novel features of construction and arrangements of parts as will be hereinafter fully described 'and pointed out in the claims, reference being had to the accompanying drawings, in which: Y

Fig. 1 is a side view in cross section of my device.

Fig. 2 is a front view of my device.

Fig. 3 is a front view in cross section of my device.

Fig. 4 is a side view in cross section of a part of my device.

The same reference characters denote like parts in each of the several figures of the drawings.

In carrying out my invention, I provide a casing A, which may be mounted in any convenient manner in position for use, but in alinement with the channel flow of gas and so positioned as to form a part of the gas conduit and forming an intermediate part of the same at any convenient oint. Thru the casing A, I provide a tu ular channel B, irregular in its course and at one end of which I have means for connecting with the gas pipe C, in the iniiow and at the other end connecting with the section C for the gas outflow. IIransversely with this channel in casing A, I have inset three bevelled tubular valve seats 2, in which I mount in any convenient manner the bev elled rotating valves 3 adapted to be properly tted to the seats. Transversely thru the valve bodies 3 I have the sloping tubular openings A the opening ends in which are positioned in alinement with the adjacent openings in the transverse tubular channel B and forming part of the same. The tubular valve bodies 3 have at their outer end an outwardly projecting reduced stem eX- tension 5, thereby, in this construction, forming a shoulder 6 on lthe valve body. The valve body may be so constructed that theshoulder 6' is on a plane with the outer surface of `the casing A or it may be of lesser length, than the valve seat and slightly below the surface of the casing A and thus forming'a recess for the insertion of any suitable packing material. The stem 5 immediately adjacent to the shoulder 6 of valve 3 is circular in form 7, while beyond this round surface 7 it projects in octagonal form 8. Mounted over the stem 5 and shoulder 6 and extending to the surface of the casing A, I have mounted the plate 9 having a circular opening therein adapted to lit the rounded surface of the stem 5 and held in position by the screws 10 in one form of construction, mounted in the surface of the valve casing A. Over theV octagonal section of stem 8, I mount the cap ll, its inner surface adjacent to the plate 9 and its outer surface projecting *into the turn handle formation l2. This turn cap l2 may be mounted on stem 5 and held in position on stem 5, either by set screw 14e or by any other convenient method. On the face of plate 9, in any convenient position, I have the pointer mark 13 and on the outer surface of cap l0 I have marked a series of indicator numbers from l to 8 as shown in Fig. 2. In the union between the ends of the tube section and the casing A, I make the connection in any convenient manner, either by sockets let into the ends of the casing as shown Ain Fig. l or in anyk other convenient manner or by threaded connection or by soldering or brazing or in a manner making the tubing an integral part of the casing.

In the construction of my device as to the mounting of the valves and the method of turning the same, the position and mounting of the dials and the manipulation of the same in connection with the marker, I elect to use any other appro riate means for mounting an adjustment ciffering in details but without departing from the spirit of my invention.

In the operation of my device, the casing A having been properly positioned for use in connection with the gas conduit, I form a combination of numbers which I term, the combination, indicating the position of opening a continuous gas conduit thru the llfl Cil

casing. I then so turn the valve that the transverse openings therein are all in aline-` mentw'ith the tubular opening 1n the casing.
